Lecturer: Prof. Dr. Hans A. Weidenmüller Affiliation: Max-Planck-Institut für Kernphysik Abstract: The phase of the transmission amplitude for electrons traversing a quantum dot shows the same pattern for long sequences of consecutive resonances. Such universal behavior is caused by correlations of the signs of resonance transmission amplitudes. I discuss the stability of such correlations in terms of a statistical model. If the dot is classically chaotic, the resonance eigenfunctions have a Gaussian distribution. Under this hypothesis, long sequences of resonances with universal behavior persist in the semiclassical limit for dots with large electron numbers and for specific energy intervals. Numerical calculations are quantitatively closer to universality, showing the limits of the Gaussian hypothesis. ‏האירוע הזה כולל שיחת וידאו ב-Google Hangouts. הצטרף: https://hangouts.google.com/hangouts/_/mail.huji.ac.il/tba-prof-dr?hceid...
